The LP5816 is a 4-channel RGBW LED driver. The device has ultra-low operation current with 0.1µA (typical) in shutdown mode, 0.1mA (typical) when enable device and 0.2mA (typical) when illuminate LEDs.

Both analog dimming and PWM dimming methods are adopted to achieve powerful dimming performance. The output current of each LED can be adjusted with 256 steps from 0.1mA to 25.5mA or 0.2mA to 51mA. The 8-bits PWM generator enables smooth and audible-noise-free dimming control for LED brightness.
